BIB.

Application tiled January 11, 1922. Serial No. 528,367.

'He it known that l. ALFRED B. LEWIS, Va a'it'izen ot the United States`and a resident fit Philadelijihia, county of Philadelphia, l'Fitate otPenns'ylvania` have invented certain nav.' and useful Improvements inBibs, ot' which the following is a specification.

Some ot the objects ot the present invention are to provide an improvedbib or faucet tor controlling the flow of Water or any' other liquid: toprovide in a bib of valve construction whereby leakage is etfectuallyprevented when the valve is closed; to provide a bib arranged to breakthe pressure of Cie liquid medium and prevent splashing thereof as saidmedium is discharged from he bib: to provide improved means for takingup or compensating' for ive'ar upon the valve parts ot a bib or faucet;and lo-provide other in'iprovements as will hereinafter appear.

In the accompanying drawings, Fig. l represents a ,side elevation,partly in Section. oit.' a bib or faucet embodying one form ot thepresent invention: Fig. 2 represents a section on line 2-2 ot Fig`1;-Fig. 3 represents a. section on line 3 3 of Fig. 1; Fig. lrepresentsa side elevation of the valve member; and Fig. 5 represents a plan ofthe valve member.

Referring to the drawings, one form of the present invention comprises abib 0r 'faucet body 10, ot' tubular construction having an inlet port 11and a discharge port 12. ln the present construction, the inlet port 11is formed in a partition 13 extending transversely ot a head 14, whichforms a fixed part ot' the body 10, and the discharge port is formed ina nozzle 15 which forms the nov-able part of the body 10.

For the purpose ot controlling the inlet port 11, it is provided at itsouter side with ":n annular flange 1G which forms a seat for a valvemember 17 arranged to be moved axially towards and away from the flangedseat- 16 according to requirements. The valve member 17 is preferablyprovided with a removable Washer 18 or other leakproot member arrangedto seat over the 1net port 11 to cut off the supply of liquid, gas, orany substance adapted to traverse the bib.

In order to maintain the valve member 17 in proper operative relationwith respect to the inlet port 11, it is provided with an axiallydisposed stem 20. arranged tor tree sliding movement in a guide opening21 -lormed in a web 22, which 'extends transversely Within the nozzlebody7 15, the parts being so arranged as to accurately align the valvemember 17 with the inlet. port 11.

As a means f'or permitting the lloiv ot liquid when the valvej17 isopen, and also breaking the pressure of the fluid so that it dischargesthrough thenozzle 15 with diminished velocity and a lminimum ofsplashing, the valve member .17 has a diameter slightly less than theinner 'diameter ot the head 14, While its outer,,periphery is providedwith a plurality of through grooves 23, which serve to .delivertheliquid to the nozzle 15. Inv assembled condition the ar rangement ot theparts is such that the web holds the val've member 17 Within the head11iI in both the open and the closed positions ot' the valve member 17,and as a consequence when the vvalve 17 is open the incoming'column ot"fluid under lpressure iin- ;jacts against the .upper faceot the valvemember17,.isbroken-up, and then spreads radially tol all thecircumferential grooves 23. Leaving the grooves 23 the liquid enters anenlarged, circumferential chamber 24 forming the inlet portion of thenozzle 15, the sides of which converge downward lo the discharge port12.

For controlling the opening and closing of the valve member 17, theupper end of the body of the nozzle 15 is provided with an internalthread 25 arranged for co-operative engagement with an external thread26 upon the head 14, and has also a cylindrical external neck 27 forminga shoulder 28. A ring 30 is arranged to tit over the neck 27 and seatupon the shoulder 28 with its upper end flush with the upper extremityof the nozzle body 15. The neck 27 is provided with a plurality ofcircumferentially arranged depressions or holes 31 into any one of whicha set screw 32 or the like is arranged to fit to lock the ring 30 in itsadjusted position. An extension 33 projects laterally from the ring 30at a convenient point to form a handle for turning the ring 30 and itsassociated parts. By this construction it is possible to take up forwear of the valve member 17 by loosening the set screw 32, turning thering 30 relative to the body l,10,and locking it inthe new posi` tion.by setting the screw 32v in another of the openings 31.

.In orderfto reduce the inertia of the inevino column ofliquid beingsupplied to the bi an extension pipe 34 leads from the head 14 and isprovided with a reverse bend at a point preferably adjacent to the endwhere it is joined to the source of suppl)r by means ot a threaded end36. A clamping nut- 3T of thelange type is carried by the pipe PA:

for anchoring the bib to its fixed support.

It will now be apparent that a complete unitary construction has beenprovided` wherein liquid under pressure can be discharged for use withits pressure so reduced as to cause delivery Without. splashing andspattering such as takes place in the ordinary type of bib or faucet.rPhis reduction of pressure takes place in part because o't' the reversebend in the extension pipe 34E at or near the inletend thereof, and inpart to the spreading action of the valve 17 to gether With the leffectof the enlarged chamber in the Anozzle member 15. After expansion inthis chamber the liquid passes through the converging nozzle' withsuliicient velocity to prevent instant spreading and distribution of theliquid in all directions at the outlet ort 12.

yVVhi e but one form in ivhich this inven- Y tion may be embodied hasbeen here shown,

" orfthescope of the appended claims.

Having now fully described my invention, what I claim is 1. In a bib,ahead having an inlet port opening into arecess of greater diameter, avalve member' arranged to fit Within said'. recess for free slidingmovement to open or: Close said inlet port, a nozzle threaded to saidhead and having a chamber of 'larger diameter than said recess locatedon the discharge side ot' said valve member and communicating withtheioutlet of said nozzle, the peripheryv of said valve membercomprising a plurality o't axially disposed ribs to provide paths tosubdivide the {iowing liquid into a plurality of streams, and meanscooperating with said head for controlling the movement of said valvemember.

2. ln a bib, a head -having an inlet port opening into a recess ofgreater diameter, a valve member arranged' to open or close said inletport, and'having a part of enlarged diameter fitting Within said 'recessfor free sliding movement, a nozzle threaded to said hcadand having achamber ot' larger diameter than said recess located on the discharge'side of said valve member and communicatingwith the outlet of saidnozzle, means for actuating said head to control the movement of `saidvalve, the periphery of said enlarged valve member lpart comprising aplurality of axially disposed ribs to provide paths to subdivide theflowing liquid into a plurality of streams, whereby theflow pressure isreduced and splashing eliminated.
